Contagious Pneumonia in the Horse. 107 



bleeding in diminishing the blood-tension in the chest and allowing 

 the resumption of the normal vaso-motor and nutritive functions 

 without the dangers of venesection. The soothing action on the 

 skin, soothes by sympathy the infected and inflamed tissues. 



A steam or hot air bath may serve a similar purpose. Con- 

 joined with an aloetic laxative and aconite, I have seen this 

 reduce the temperature from 104.5° F- to 102.7° F. at the next 

 taking 18 hours later. It only once again reached 103"^ F. in the 

 subsequent course of the disease. 



To secure diaphoresis, warm mashes or gruels may be freely 

 used. Alcoholic drinks have been freely used (the weaker wines 

 I to 2 qts., sherry, brandy, whisky ^4 to i pint), camphorated 

 spirit (2 — ^3 drs.) subcutem, ipecacuan (i oz.), tartar emetic (2 

 drs.), liquor of acetate of ammonia (40ZS. ), pilocarpin (2 grs. 

 subcutem). If the alcoholic liquors produce a free circulation 

 and glow in the skin, better still if diaphoresis, they afe useful 

 antithermics, but, if they fail in this, they may do harm by 

 reducing the vital activities of the leucocytes, and their power 

 of resistance. Trasbot has had uniformly unfortunate results 

 with alcohol in large doses. The same objection attaches to 

 tartar emetic and other depressant diaphoretics, though valuable 

 if free diaphoresis is secured. 



Constipation may be met by cold water injections, calomel (^ 

 to I dr.), pilocarpin (3 grs.) eserine (i}4 gr.), sodium sulphate 

 or other agent graduated to requirement. 



An expectorant and alkaline diuretic action may be obtained 

 from potassium iodide (1-2 drs.), ammonium chloride (2 drs.), 

 or ammonium acetate. These not only liquify the exudate, and 

 facilitate expectoration, butlsecure elimination of toxins, ptomaines 

 and waste products from the blood and system. The iodide is 

 besides somewhat antiseptic. 



In the early stages especially medicinal antithermic agents may 

 be called for: acetanilid (2-3 drs.), phenacetin (2-4 drs.), sul- 

 phate of thallin (2-3 drs.), sodium salicylate ()4 oz.) or in the 

 weaker cases, caffein — natrium salicylate ( i dr. ) or quinine sul- 

 phate (2-3 drs.) Acetanilid will sometimes relieve djuUness, and 

 materially improve the general condition. 



In weak conditions of the heart we may resort to digitalis (10- 

 15 grs.), strychnia sulphate (2 grs.), strophanthus tincture (3 to
